The Trowmans Hole

Richard Jenkins owned a colliery at Glan-y-Wern and built a canal along the western edge of Crymlyn Bog, extending eastward to connect with the River Neath at Trowman’s Hole (now called Red Jacket Pill). This canal enabled boats to transport coal across the River Neath to the coal wharves at Giants Grave.

Jenkins secured the lease to build the colliery from Lord Vernon on August 14, 1788, but tragically died that same day. His partner, Edward Elton, took over the operation, and the canal was completed by 1790. The canal remained in use for approximately 20 years. Unfortunately, Elton went bankrupt and passed away in 1810.

No direct connection to the river was established; instead, a termination basin was constructed for unloading barges, with cargo then transferred to ships for crossing the river.

Between 1817 and 1818, George Tennant acquired the Glan-y-wern Canal and, alongside his engineer William Kirkhouse, refurbished it by adding an entrance lock. This barge lock allowed vessels up to 61 tonnes to leave the River Neath and travel to Swansea via the canal. Consequently, the original Glan-y-wern Canal was transformed into two branches off the Tennant Canal.

After enduring significant delays caused by coal barons and the Neath Canal company, who postponed constructing a lock on the Briton Ferry side, Tennant decided to extend the canal from Red Jacket Pill through Neath Abbey to Aberdulais instead.
